NCHRP Project 20-24(89) is intended to provide compelling research results to support effective decision making and inform public policy. The research being undertaken to present—in ways that are both readily understandable to a broad audience and defensible within the professional community—the role and value of transportation to the U.S. economy, by developing case studies of transportation’s part in representative industries or economic sectors. These studies will rely on available data and accepted analysis methods to produce meaningful information and present that information in ways that will resonate with stakeholders in the nation’s transportation system.
